GTA: Decision

The whole world has succumb to the undead. Day by day, thousands are eaten by zombies. Fortunately, some soldiers are fighting back even though the government give up a long time ago. As one of the few survivors save by the soldiers, my decision was to help them take back the city.
This game is about a survivor, who wants to fight and take back the city for the few survivors. He was given just a gun to defend himself. Use the gun to kill zombies and you would earn money on every kill. Use the money to buy better guns and fight back.
